Hunter,
Your main.go file is 171 lines of dense code. If you reduced your issue to
a small, working piece of code, people would be more likely help you.
You say "bufio.Scan() doesn't return io.EOF." Why?
$ go doc bufio.scanner
type Scanner struct {
}
Scanning stops unrecoverably at EOF, the first I/O error, or a token too
large to fit in the buffer.
$ go doc bufio.scanner.scan
func (s *Scanner) Scan() bool
Scan advances the Scanner to the next token, which will then be
available
through the Bytes or Text method. It returns false when the scan stops,
either by reaching the end of the input or an error. After Scan returns
false, the Err method will return any error that occurred during
scanning,
except that if it was io.EOF, Err will return nil.
For example,
package main
import (
"bufio"
"fmt"
"io"
"os"
)
func main() {
var input = bufio.NewScanner(os.Stdin)
for input.Scan() {
text := input.Text()
fmt.Println(len(text), text)
}
if err := input.Err(); err != nil {
fmt.Fprintln(os.Stderr, err)
return
}
// input.Scan() == false && input.Err() == nil
fmt.Println(io.EOF)
}
Output:
# On Linux, Ctrl-D for eof
$ go run eof.go
asd
3 asd
EOF
$
